(average)Notwithstanding the tremendous variation in sizes and materials, a typical paperclip weighs about 22 grains. The country of Norway has used the paper clip as something of a national symbol since the end of World War II based on the erroneous notion that the paperclip was invented by a Norwegian, Johan Vaaler. However, the paperclip had already been in existence for at least 30 years by the time of Vaaler patented his paperclip design.

(for Jelly Belly beans; approximate)Made of sugar, corn syrup, and pectin, a single jelly bean weighs about 18 grains. President Ronald Reagan cited jelly beans as his favorite candy and 49,000,000 grains of the candies were served at his first inauguration in 1981.

In other words, 22 grains is 0.570 times the weight of a Penny, and the weight of a Penny is 1.80 times that amount.

(United States) (formally one-cent coin) (Union shield design, 2010-present)The weight of a United States penny is 39 grains. According to a 2010 report by the United States Mint, the cost of manufacturing and distributing a penny is $0.0179 — more than its face-value.
